Let's do the twist

Good Form twist

Charles Bush

Sit upright with your right leg crossed in front of your left leg. Move your knees closer together and your feet farther apart to get your calves to cross. Inhale with your chest lifted and shoulders relaxed.

Good Form

To maintain flexibility in your hips and back, practice seated twists on the floor in a cross-legged position. If you have tight hips, sit on a firm yoga block or try sitting on a thick telephone book.

Sit upright with your right leg crossed in front of your left leg. Move your knees closer together and your feet farther apart to get your calves to cross (instead of just crossing at the ankles). Inhale with your chest lifted and your shoulders relaxed.

On an exhalation, place your left forearm to the outside of your right thigh and rotate your upper body to your right. Keep your shoulders level as you raise your right arm to shoulder height. Turn your head to the right and look toward your hand. Pause for a few breaths, inhale to expand your body and exhale to twist deeper. Return to center. Change the cross of your legs and repeat on the other side.
